    Hi Fanatics, I am in the UK and in line with government policies, E10 fuel has arrived and is now the standard unleaded fuel replacing E5. Having checked on the government website, it says all BMWs are fine to run on the new E10 fuel. So I've just wanted to ask if anyone has run on the new E10...

    Hello guys. I’ve got M54B30 in my ‘01 E46 and noticed that after I replaced the fuel pump, my LTFT on both banks are about -4 % to -7% which is almost rich condition. Now, i’ve already used the magic of reset adaptations, but after few kilometers, the LTFT readings are back to negative numbers...

    So the fuel filter I order arrived and the vacuum line nozzle thingy was crooked. I don’t know if it has been bent during transports or if it’s factory error. I can’t see any obvious cracks or anything. So is it safe to use? Or should I consider buying a new one?

    Hi, can anyone help. I've purchased a new fuel pump by Bosch. I checked part numbers on real oem using the vin and ensured the specific numbers matched yet the new pump is significantly smaller as you can see in the first picture. The car is a 2002 330 ci. My question isn't so much what do I do...

    Hello all! I am just getting started into learning about ECU tuning. I watched a really good series on Youtube (video at bottom of post) that talked about the general process of tuning. Someday in the far far future I would love to turbo my car (325i) so I am trying to apply what I learned in...

    Hi! I really need some help. I've got a 2005MY 320D, which, about a month ago wouldn't start. I towed it to my local BMW workshop to have the problem identified, and after a while they told me that the pre-supply fuel pump was faulty and needed replacing. Being young and a student, naturally I...

    I recently diagnosed a Fuel Sending Unit error after driving around with my fuel gauge on empty for a while. Driver side unit checked out, but the passenger side unit on the fuel pump was reading as bad. Since the pump has been working fine, I didn't want to have to replace it just because of...

    So I have replaced the oem headers with aftermarket catless headers. I’ve been driving with CEL on and I want to try and fix the misfiring problems. I’ve got 3 misfires on my engine. I only have the o2 sensors that go before the cats on and the ones after the cats are off. Recently I have...

    Hey everyone, Been noticing the past few days that my fuel gauge doesn't actually show that I am using any fuel, even though I am driving in excess of 120km per day. It initially settled at just above 1/2 a tank, I filled up the tank completely and now it shows full all the time, even after...

    Hello fellow fanatics :D , I just want to get some insight on the last of my problems. So after getting rid of my CEL's related to vacuum leaks, I am left with two more. I am currently pulling a P0441 (Incorrect purge flow) and a misfire with low fuel cut off. So I have researched the P0441...

    So I'm guessing my fuel pump is saying goodbye as I'm having trouble turning the car on. I searched the forums and siemens/VDO pumps were recommended, but has anyone tried AEM? I'm currently looking at this one...
